This article presents a digital fabrication method for a speech aid prosthesis by using a 3D-printed polyetheretherketone (PEEK) framework. The computer-aided design (CAD) of the speech aid prosthesis framework was based on oral scan data. The framework was printed with PEEK filament material supplemented with nanoTiO powder by fused deposition modeling (FDM). A resin preliminary cast was 3D printed, and an altered cast technique was adopted to fabricate the definitive cast. The PEEK framework exhibited precise fit, toothlike color, excellent mechanical properties, and reduced weight as compared with a typical metal framework. This technique describes the successful clinical application of 3D-printed PEEK material for the fabrication of an adult speech aid prosthesis.
本文提出了一种使用 3D 打印聚醚醚酮（PEEK）框架制作语音辅助假体的数字化制造方法。语音辅助假体框架的计算机辅助设计（CAD）基于口腔扫描数据。该框架采用 PEEK 灯丝材料打印，并辅以纳米 TiO2 粉末，通过熔融沉积建模（FDM）成型。首先 3D 打印树脂初步模型，然后采用改良的铸模技术制造最终的铸模。与典型的金属框架相比，PEEK 框架具有精确的贴合度、牙齿般的颜色、优异的机械性能和减轻的重量。该技术成功地将 3D 打印 PEEK 材料应用于成人语音辅助假体的制作。
